My firewall log at home and at work are filled with attempts to connect to 28916 all udp traffic from thousands of ip addresses. I cannot figure out what this port normally does and why they keep trying to connect so much. 16% of all incoming connections at my home have a source port of 6881 so that makes me think it has something to do with bittorrent, but my work doesn't ever use bittorrent. One ip address has 6210 attempts to connect and counting, starting over two months ago. Anyone else seeing this in their logs?

BTW, the logs at my home are from the last 54 days (odd number huh, that's when I got my m0n0wall up and running)
